Abstract

Abstract: There are many factors which influence cracks of cement concrete pavement.First,this paper analyzes the dynamic response by moving vehicle,and constructs a dynamic model of a slab(beam) rested on a viscoelastic foundation.Then the effects of displacement and strain and fatigue cracks in pavement slab by vehicle road interaction are discussed.The aim of the paper is to provide methods to prevent cement concrete pavement from cracking.

Key words: cement concrete pavement, vehicle road interaction, displacement and strain, fatigue cracks in pavement

摘要： 水泥砼路面开裂和破坏的影响因素较多,情况也比较复杂 .笔者首先分析路面板在运动荷载作用下的动力响应,建立粘弹性地基上板的动力模型,然后从理论上探讨路面不平整引起的车板耦合作用对路面板的挠度、应变及其路面疲劳开裂的影响,从而为水泥砼路面的抗裂研究提供依据

关键词: 水泥砼路面板, 车板耦合, 挠度和应变, 疲劳开裂
